StarTech ICUSB2321FIS USB to Serial RS232 Adapter
Overview
The StarTech ICUSB2321FIS provides a robust USB 2.0 to RS232 serial connection, essential for integrating legacy industrial equipment, point-of-sale terminals, or specialized surveillance devices into modern networks. Its integrated 2500 Vrms optical isolation and 500W bi-directional surge protection circuits safeguard connected equipment from electrical transients and ground loops, making it suitable for environments with potential power fluctuations or sensitive instrumentation. This adapter is powered directly from the USB port, eliminating the need for an external power supply.
Compatibility
This adapter is compatible with systems running Windows, macOS, and Linux. It supports standard RS232 serial communication and is ideal for connecting devices such as barcode scanners, modems, printers, and console ports on network switches and routers. The FTDI FT232RL chipset ensures broad compatibility with most serial communication software and drivers.
Installation Notes
The adapter supports data transfer rates up to 921.6 Kbps, allowing for efficient communication with high-speed serial devices. It supports 7 or 8 data bits, 1 or 2 stop bits, and various parity modes (None, Odd, Even, Mark, Space) for flexible serial configuration. The 256-byte FIFO buffer helps manage data flow, reducing the load on the host CPU. The integrated 2.5-meter (8.3 ft) cable provides ample reach for most installations.
